# WooriDB
[USER GUIDE](https://naomijub.github.io/wooridb/)

WooriDB is a general purpose (**EXPERIMENTAL**) time serial database, which means it contains all entities registries indexed by DateTime. It is schemaless, key-value storage and uses its own query syntax that is similar to SparQL and Crux's Datalog.

Some other features are:
- Hashing keys content with [`ENCRYPT`](https://github.com/naomijub/wooridb#create-entity) keyword.
- Hashed values are filtered out and can only be checked with [`CHECK`](https://github.com/naomijub/wooridb#checks-validity-of-of-an-encrypted-key) keyword.
- [`Ron`](https://github.com/ron-rs/ron/blob/master/docs/grammar.md) schemas for input and output.
- [x] JSON is supported via feature.
- Entities are indexed by `entity_name` (Entity Tree), `DateTime` (Time Serial) and `Uuid` (Entity ID). Entity format is a HashMap where keys are strings and values are supported [`Types`](https://github.com/naomijub/wooridb/blob/main/wql/src/lib.rs#L78).
- Stores persistent data locally.
- Able to handle very large numbers when using the `P` suffix.
- Ex: `98347883122138743294728345738925783257325789353593473247832493483478935673.9347324783249348347893567393473247832493483478935673P`.
- Configuration is done via environment variables.
- Authentication and Authorization via session token
- [Conditional Update](https://naomijub.github.io/wooridb/sec-6-tx.html#match-update)
- Some Relation Algebra
- Entity history

`Woori` means `our` and although I developed this DB initially alone, it is in my culture to call everything that is done for our community and by our community **ours**.

## Installation

To run WooriDB it is necessary to have Rust installed in the machine. There are two ways to do this:

1. Go to rustup.rs and copy the command there, for unix it is `curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh`.
2. Clone WooriDB and execute `make setup`.

### Executing WooriDB

- `Release mode performance`: `make release` in project root for performance optimization.
- `Release mode size`: `make run` in project root for size optimization.
- `Debug mode`: `make debug` in project root.

### Docker
you can find the latest docker image at **[naomijub/wooridb](https://hub.docker.com/repository/docker/naomijubs/wooridb)**. The current most stable tag is **`beta-8`**. To execute the docker container run:

* `docker run -p 1438:1438 naomijubs/wooridb:beta-8 debug` for debug mode.
* `docker run -p 1438:1438 -e AUTH_HASHING_COST=8 -e ADMIN=your-admin-id -e ADMIN_PASSWORD=your-admin-pswd naomijubs/wooridb:beta-8 run` for size optimization.
* `docker run -p 1438:1438 -e AUTH_HASHING_COST=8 -e ADMIN=your-admin-id -e ADMIN_PASSWORD=your-admin-pswd naomijubs/wooridb:beta-8 release` for performance optimization.
* All `-e/--env` can be replaced by a `--env-file path/to/your/.env`. Your `.env`file should contain the following fields:
```
HASHING_COST=16
PORT=1438
AUTH_HASHING_COST=8
ADMIN=your-admin-id
ADMIN_PASSWORD=your-admin-pswd
```

## Usage
* Responses are in [`RON`](https://github.com/ron-rs/ron) format. Support for `JSON` is via `--feature json` and `EDN` will be done later by using features.
* For now only persistent local memory is used. Support for `S3`, `Postgres` and `DynamoDB` will also be done later by using features.
* **Precise floats** or **numbers larger than f64::MAX/i128::MAX** can be defined with an UPPERCASE `P` at the end.
* _Note_: This type cannot be updated with `UPDATE CONTENT`.
* Ex.: `INSERT {a: 98347883122138743294728345738925783257325789353593473247832493483478935673.9347324783249348347893567393473247832493483478935673P, } INTO my_entity`.
* `BLOB` will not be supported. Check out [To BLOB or Not To BLOB: Large Object Storage in a Database or a Filesystem](https://www.microsoft.com/en-us/research/publication/to-blob-or-not-to-blob-large-object-storage-in-a-database-or-a-filesystem/).
* To configure hashing cost and port some environment variables are required:
```
HASHING_COST=16
PORT=1438
```

### File approximated size

For ~10000 entries in a day, the file size will be 2.5 GB for registries (and for cached values - this may become an issue soon). After compression it can be reduced to 10% of this.
